By synchrony I mean in phase EEG. Coherence us a general
case-stability of phase relation--and synchrony is a specific
case--stability of phase relation and in phase<br>

Hi Fred,

</div>
<div>what do you mean by synchrony? </div>
<div>To caclulate some of additional connectivity measures, you
might want to try SIFT, an EEGLAB associated toolbox and plugin.
It will allow you to compute Granger Causality based measures
such as partial directed coherence. It will also allow you to
compute many other measures including the popular directed
transfer entropy.</div>

<div>Hope this helps,</div>
